How do I find if my a table is MyISAM or Innodb [duplicate]

Answer 1

You can use SHOW TABLE STATUS to see table information.

SHOW TABLE STATUS WHERE `Name` = 'my_table';

Simply check the value of the Engine column in the returned dataset to know which engine the table is using.

Answer 2

SELECT ENGINE
FROM INFORMATION_SCHEMA.TABLES 

WHERE TABLE_NAME='your_table_name'
AND   TABLE_SCHEMA='your_database_name';
-- or use TABLE_SCHEMA=DATABASE() if you have a default one.

Answer 3

You can use SHOW CREATE TABLE and look for the ENGINE part in the response.

SHOW CREATE TABLE users;

Example:

CREATE TABLE innodb_table (id int, value int) ENGINE=INNODB;
CREATE TABLE myisam_table (id int, value int) ENGINE=MYISAM;
CREATE TABLE default_table (id int, value int);

Result for innodb_table:

SHOW CREATE TABLE innodb_table;

| Table        | Create Table                                                                                                                     |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+

  `id` int(11) DEFAULT NULL,
  `value` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

Result for myisam_table:

SHOW CREATE TABLE myisam_table;
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| Table        | Create Table                                                                                                                     |

  `value` int(11) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

Result for default_table:

SHOW CREATE TABLE default_table;
+---------------+-----------------------------------------------------------------------------------------------------------------------------------+
